To all whom it may concern.-

Be it known that I, ROBERT F. W. BEARDs- LEY, a citizen of the UnitedStates of America, residing at Chicago, in the county of Cook and Stateof Illinois, have invented certain new and useful Improvements inMachines for Pasting Up the Ends of Cartons and the Like, of which thefollowing is a specification.

My invention relates to certain machines for pasting up the ends ofcartons and the like; and it consists in certain novel devices andcombinations thereof adapted to fold together the ends of the cartons,to apply paste to the same in the necessary places, and to press theends together in the proper relation to effect a complete closure of theend of the package.

My invention is illustrated in the drawings, of which-- :0 Figure l is aplan View. Fig. 2 is a view similar to Fig. l with the carrier removedand certain other portions broken away. Fig. 3 is a side elevationlooking from the arrow 3 of Fig. 1. Fig. 4 is a longitudinal vertical :5section in the plane 4 4 of Fig. 1 looking in the same direction as Fig.3. Fig. 5 is a trans- .verse vertical section in the plane 5 5 of Fig. 1looking in the opposite direction. Fig. 6 is a vertical transversesection in the plane 6 6 of Fig. 3 looking in the direction of the arrow6. Fig. 7 is a vertical transverse section in the plane 7 Tot Fig. 2looking in thedirection of the arrow 7. Fig. 8 is a detail verticalsection in the plane 8 S of Fig. 4. Fig. 9 isa detail vertical sectionin the plane 9 9 of Fig. 2, the section being taken toa sufficient depthonly to show an adjustable bearing. Fig. 10 is a detail perspective of apush-bar adapted to crowd the carton off of the carrier. Fig,

11 is a detail section similar to Fig. 4, upon a larger scale, andshowing the end of one of the carrier-blocks with a carton thereon,showing the portion of the device which operates to fold in two oppositeflaps prior to the application of the paste. Fig. 12 is a detail sectionin the plane 12 12 of Fig. 4, differing from said figure, however, inshowing one of the carrierblocks in the section to illustrate the mannerin which the remaining two opposite flanges are spread apart for theapplication of the paste.

showing-the carrier-block in the section and 7 illustrating the turningin of the last flap of the carton. Fig. 16 is a detail section in theplane l6 16 of said Fig. 4, showing the carrier-block in that plane andillustrating the position of the end portions of the cartonjust prior totheir passage upon the pressure-belt and rollers; and Fig. 17 is aperspective of one end of a carton, showing the position of the partsthereof prior to their passage through the machine.

Referring to Fig. 17, one end of a carton A is shown rectangular intransverse section and having the various sides thereof extending attheir ends in the form of flaps a a a a separated from each other at thecorners. The machine of this application is devised to turn in the flapa first, then turn in the flap a on top of the former, then to applypaste to the inner surfacesot' the flaps aa then to turn in the flap aon top of the two already turned in, then to turn down the flap a on topof all the others, and afterward to apply sufficient pressure to theflaps to glue the flap a upon the top of the flaps a a and the flap a ontop of the flap a, making a stiff and tight end for the carton, afterwhich the latter is automatically thrust from the carryingblock, leavingthe latter in position to receive a new carton.

Taking up the machine itself andlooking at Figs. 1 to 4, the frameworkwill be seen to consist of two triangular open side pieces B B, restingupon legs I) b 19 79 secured together by transverse bolts 1) b andtubular struts bib Upon the side portions of the same near theright-hand end are triangular extensions b b. The side portions of theframe are provided with three transverse bosses b b b. The bosses b I)are drilled to provide bearings for the main driving-shaft of I02 themachine 0, and the bosses Z) Z2 upon one side are bored to receive pins0 0, upon which are mounted intertneshing gears 0 0 the former of whichis in mesh with a gear 0 on the driving-shaft C. Driving-pulleys c c,preferably fast and loose, respectively, on the driving-shaft, providemeans for imparting power thereto. In the upper portion of the machineare two opposite bearings b 1) in which is journaled a shaft D, havingfast upon it a gear (I, in mesh with the gear 0 and a rotating carrierd, provided with radially-projecting carrier-blocks E E E E Figs. 3 and4, preferably hollow and slotted longitudinally through their oppositesides at 6. These blocks are provided with an adjustable stop (2,slotted at c and adjustably secured to the blocks by means of bolts eThe stops are provided with guides c", diverging from-the blocks toprevent the end of the carton from passing over the stop. The gearingdescribed rotates the carrier in the direction of the arrow 00, seen inFig. 4, and the carrier-block E is shown in said figure in properposition to receive a carton, which is slipped over said block and isintended to fit closely thereon, with the loose flaps shown in Figs. 17extending beyond the end of the carrier-block. Just back of each one ofthe carrier-blocks is a bracket F, secured to the carrier and providedwith a stud f, upon which is journaled a gearf,carryingatangentially-projecting fingerf bentat the pointf to fitclosely over the corner e of the carrier-block when brought into properposition by the rotation of the gear. A short rack f meshes with thegear and is secured to the end of a Sliding rod f guided longitudinallyin a lateral extension F of the bracket F and in the carrier at e. Theinner end of the rod bears a fork f, confining between it and thecarriera coiled spring f and embracing between its two arms a rollerfrunning upon a cam f secured to the end of a sleeve F Figs. 1 and 5,fastened to the frame by means of a flange F The cam being stationary,the rollersf travel over its periphery, and during the passage of one ofthe carrier-blocks from the position of the block E in Fig. 4 to theposition of the block E the rollerf runs up to the point of the cam,pushing the rod f outward, rotating the gear f, and swinging the fingerf around into the position shown in connection with the carrier-block Ein said figure and folding in the flap a upon the end of thecarrier-block, as is shown in Fig. 11.

As the roller runs 0% of the point of the cam the opposite flap of thecarton a strikes the upper end of a guide-plate G and is folded down ontop of the flap a This guide-plate is preferably made in two parts g g,Fig. 2, secured together by screws g 9 Fig. 4, so as to be capable ofadjustment as to Width when desired. It has a concave face g on the sideof and concentric with the carrier, which holds the flaps to a inposition as they pass over it, and oppositely-extending wings g g"reacts converging toward the top, so as to permit the flaps Ct a topass on opposite sides and to spread the same apart into the positionseen in Fig. 12. This guide-plate is supported upon a transverse shaft gsecured against rotation at its opposite ends in the triangularextensions b Z)" of the frame. The shaft is grooved within the shoe toprovide a longitudinal rib g which is held between two adjusting-screwsg g, providing means for angular adjustment of the plate upon the shaft.

On the main driving-shaft Q are a pair of gluing-wheels H H, theperipheries of which extend toward the carrier sufficiently to come incontact with the outspread flaps of the carton and the lower portions ofwhich run in a glue-pot 1, containing glue J, the pot being providedwith a hot-water chamberi,heat ed by means of a steam-pipe 2'. Across-bar K, secured to the frame, is provided with sockets 7c, in whichare held scrapers k by means of set-screws 7.3 A screw 70* providesmeans for nice adjustment of the scraper toward or from thegluing-wheel. Upon opposite sides of the gnide-plate G arms M M, Fig. 1,are supported upon the shaft 9 so as to be angularly adjustable thereonin the same manner as the plate G. The free ends of these arms areprovided with pins m m, carrying rollers m m extending over and almostin contact with the gluing-wheels. As the carton passes onward from theposition shown in Fig. 12 the outspread flaps pass between these rollersand. the gluing-wheels, as is shown in Fig. 13, and receive therequisite amount of glue upon their under sides.

Looking at Figs. 2 and 7, two plates N N will be seen secured to theopposite sides of the frame and extending inward toward each other,being bent upward slightly, as shown in Fig. 7. On the inner ends ofthese plates are secured guides at n, extending downward and adapted toreceive the carton between them. To the lower end of the guide 11 issecured a plate 71 and to the lower end of the guide a is seen red aplate 11?. The plate n is provided with a bracket 07;, forming anextension of the guide a, and with an oblique edge a, which engages the(lap a after it leaves the gluing-wheel (for which purpose its end isturned upward, as seen in Fig. 4) and folds said flap inward upon thetwo already resting against the end of the carrierblock, which are heldin that position during the operation by means of a curved rod w,secured to the guide-plate G and forming a narrow continuation of thesurface thereof. The plate a is provided with an oblique edge or,against which the flap (t strikes after the flap a has been folded inand by means of which the flap a is folded inward and upward against theother three flaps, completing the folding of the end of the box, whichis now ready to pass onward to the pressingrollers.

Looking at Figs. 2, 4, 5, and 6, two rollerframes 0 will be seen, eachcomposed of an arc-shaped portion 0, having at its opposite endslaterally-projecting studs 0 0 se cured to the respective side piece bymeans of screws 0 0 Brackets 0 upon these rollerframes assist insupporting the plates n M, as seen in Fig. 5. Each of the arc-shapedportions of these frames is provided with a series of guides 0 and aseries of springsockets 0 Between the guides are arranged aseries ofjournal-blocks 0 held in radial adjustment,Fig. 8, between coiledsprings P in the sockets and screws 1), threaded in plates P, secured tothe roller-frames by means of bolts p19 Fig. 5. Jam-nuts p preventaccidental displacement of the screws 1), and corresponding screws 19',held by jam-nuts 13 are threaded in the bottom of the sockets andprovided with disk-shaped upper ends 19 to bear upwardly against thesprings. By these devices the limit of upward movement of thejournal-blocks is made adjustable, also the tension of the springstending to hold the blocks up to said limit. Between the oppositejournal-blocks are journaled rollers Q, having gudgeons q q, journaledin said blocks.

Looking at Figs. 3 and 9, brackets R R will be seen secured to theopposite side portions of the frames by means of screws 1 1'', extendingthrough slots 4' r in the brackets. An adjusting-screw 7" provides meansfor a nice adjustment of the bracket. In these brackets is jonrnaleda'transverse shaft S, Fig. 4, carrying a driven pulleys and adriving-pulley s, carrying a belt .9 running over the rollers in thedirection shown by the arrow y and preferably at a speed slightlygreater than that of the cartons as they pass over the belt. This isdesirable, because in the various operations of guiding, spreading, andfolding the flaps areliable to be forced backward out of shape, and thegreater speed of the belt tends to advance them while setting the glue,so as to bring them back into proper relation. The tension of the beltis adjusted by the brackets just described, so that the effect of thebelt may be nicely gaged to put the finishing touches on the carton andbring the parts up square and true. During the passage of the cartonover the rollers and the belt the glue is suliiciently set to completethe operation as far as the gluingdown of the flaps is concerned. Itremains merely to force the carton from the carrier-block, and this iseffected by means of a series of push-bars '1, Figs. 10, 4, and 5, thebent ends i of which extend transversely through the slottedcarrierblocks and are preferably serrated, as shown, at t, Fig. 10, toprevent slipping of the end of the carton thereon. The shanks t of thepush-bars extend inwardly, as seen in Fig. 5, and are pivoted at theirinner ends at t to the inner ends of the levers U, pivoted between theirends at u to brackets to, Fig. 4, on the carrier and carrying at theirouter ends rollers a in position to engage a cam V, secured to the sideframe B at n, Fig. 1, and having a curved surface '0, adapted to crowdthe outer ends of the levers U inward sufficiently to shove thepush-bars out toward the ends of the slots and crowd the cartons fromthe carrier-blocks. Coiled springs W, stretched between the outer endsof the levers U and the extensions F of the brackets F, tend to draw thepush-bars toward the center of the carrier.

The carrier-block E in Fig. 4c shows the position in which the cartonhas been forced from the carrier-block, and in passing from thisposition to that of the block E in the same figure the roller upon theinner end of the lever runs off of the cam V and the spring W withdrawsthe push-bar into the position seen in connection with saidcarrier-block E.
